I'm trying to estimate the amount of CO2 remaining in my tanks. I know that most steel 5# tanks have a 7# empty(tare) weight. I also have a 10# and a 20#(or 15#) all made of steel. My question is: what is the app. tare weight of the larger cylinders? I can't find any TW stampings on them. Any help is appreciated

I would buy a dual guage regulator.____________________________________________

All a two guage regulator tells you is that you have some (or none) liquid left in the cylinder. It offers no clue as to how much. You need to weigh the tank to determine that. Thanks anyway for the reply. Does anyone know the app tare weights of those steel cylinders?

Tare weights of steel cylinders are variable due to variances in the manufacturing process, that is why almost every steel cylinder has the tare weight stamped into it. Should be right near the hydro cert date...
If your cylinders really aren't marked, your gas supplier or hydro cert shop should be able to measure and stamp them with the proper tare weights for you.
Good luck!

I have a 20lb bottle (steel) that I keep exchanging when empty. The empty weight is usually 29 to 30 pounds. The full bottles come in at 49 to 50 pounds. Not an exact answer, but when the bottle is in the low 30lbs range it's near replacement, if you don't have a high side gage to check.
